Choosing the Right Gemini API Model ID — stable vs latest vs preview vs experimental
A practical guide to the model IDs the Gemini API exposes — stable short names, -latest aliases, preview and experimental tags — with production guidance and fallback patterns.
A Tiny RAG Stack With Gemini + sqlite-vec — Production Patterns for Solo Developers
If you have been holding off on adding RAG to your personal app because Pinecone's monthly fee or Qdrant's memory footprint felt like overkill, this guide is for you. We walk through a production-grade design that runs on a single server, pairing Gemini's embedding API with sqlite-vec, with working code you can lift straight into your project.
Building an Obsidian Plugin with the Gemini API: A TypeScript Guide to AI-Powered Note Enhancements
A TypeScript walkthrough for wiring the Gemini API into an Obsidian plugin — minimal shell, settings tab, summarize-selection command, related-note suggester, and three gotchas worth fixing before you share it.
Persisting Gemini API Chat History in Redis - A Scalable Session Design
Holding Gemini API ChatSession objects in process memory breaks the moment you deploy to Cloud Run or scale horizontally. Here's why the naive 'just JSON.stringify and SET' Redis pattern falls over in production, and how to rebuild it with TTLs, trimming, locks, and a stable on-disk format.
Safely Migrating Gemini Model Versions with Shadow Traffic — A Production Pattern for Measuring Output Drift
Stop treating Gemini model migrations as a coin flip. This guide walks through a production-ready shadow traffic architecture — duplicate real inputs to the new model, quantify output drift, and cut over progressively. Includes Python and Cloud Tasks code you can ship today.
Gemini Context Caching as Margin Engineering — Protecting a 70% Gross Margin Instead of Cutting Prices
Treat Gemini's Context Caching not as cost reduction but as margin engineering — a practical playbook for protecting 70% gross margin, with cache-hit tuning, cost simulation, and pricing decisions for solo SaaS operators.
Gemini Gems Custom Instructions — Practical Best Practices That Actually Move the Needle
How to design custom instructions for Gemini Gems as a living specification rather than a static blob of text. Three complete examples — document editing, SQL coaching, and meeting notes — with the failure modes to avoid.
Migrating from Gemini 2.0 Flash to 2.5 — Where the Code Actually Needs to Change
Moving from Gemini 2.0 Flash to 2.5 is more than a string replace on the model name. Here are the six points I check every time, from temperature behavior to system instructions and output schemas.
The Gemini API Error Handbook — 401 / 403 / 404 / 429 / 500 / 503, Diagnosed by Symptom
A field handbook for Gemini API errors, organized by HTTP status and visible symptom. Covers auth, model naming, quotas, safety filters, region issues, and SDK pitfalls — with a retry strategy designed for production.
Gemini 2.5 Pro API: Cost Design Basics Before Building a Paid Chat Service
Individual developers can now build profitable chat services. But low API costs don't equal profitability. We'll walk through Input/Output pricing, Context Caching, and Batch API strategies that reduce costs by 40%—with real numbers.
Reading a 200-Page Contract with Gemini 2.5 Pro — Five Techniques That Move Long-Context Analysis to Production Quality
Using Gemini 2.5 Pro's long context for real business work takes more than stuffing the whole document in. Here are the five techniques I found most effective for contracts, meeting minutes, and technical specs.
gemini-2.5-pro-latest— Model Aliases, Parameters, and Production Patterns
